Difference between revisions of "Connect to private/dovecot-auth failed"

Revision as of 01:09, 7 October 2010

A more complete and generalized version of this message is:

servername nss-mysql[number]: warning: SASL: Connect to pipe failed: No such file or directory

Where:

servername is the network name of the machine generating the error
number is an integer, significance unknown (it seems to be a standard thing in mail.log files)
pipe is the filespec of a pipe for communication between Postfix and Dovecot, typically "private/dovecot-auth"
- (is "pipe" correct, or do I mean "socket"? not sure.)

In one particular scenario, it is preceded by an SMTP connection attempt from a remote server, and followed by a fatal: no SASL authentication mechanisms error message.

Oct 3 07:42:32 rizzo nss-mysql[26619]: fatal: no SASL authentication mechanisms

Oct 3 07:42:33 rizzo postfix/master[4272]: warning: process /usr/lib/postfix/smtp

In this particular case, a fix involved the following:

ls /var/spool/postfix/private
look for pipe with "auth" in the name
modify Dovecot's dovecot.conf file so that the auth default section includes at least the "client" section shown here, but with the "path" parameter pointing at your actual auth pipe.

If that doesn't work, go to the Postfix and Dovecot web sites and read up on SASL, especially this section.
